“We have informed the court that Mukerjea is suffering from suspected dengue and her platelet levels have gone down to 65,000,” a jail official said.

He further told PTI that doctors from JJ hospital are attending to Indrani in the prison and if its imperative to admit her, then she will be taken to the hospital.

The jail officer’s report, submitted to Magistrate R V Adone, came after the court yesterday directed the prison authorities to produce Indrani in view of the application made by CBI seeking her voice samples.

The central probe agency had told the court yesterday that it had got hold of some call records which purportedly featured her voice, and therefore it wanted her voice sample for verification.

The local court on October 19 had extended the custody of Mukerjea, her former husband Sanjeev Khanna and her driver Shyamvar Rai till October 31.

On September 7, a fortnight after their arrest and prolonged interrogation, the court had remanded Indrani and Rai to judicial custody till September 21, which was later extended till October 5 and further upto October 19.

A day after on September 8, Khanna too was remanded in judicial custody.

Indrani, Khanna and Rai have been arrested on the charge of murdering 24-year-old Sheena and disposing off her body in a Raigad forest in April 2012.

The police had exhumed remains of a body from Raigad forest and later claimed that digital superimposition of the profile of Sheena had matched with the skull recovered from the forest.

The police have also extensively grilled Indrani’s husband Peter Mukerjea, though he is not an accused in the case. Others questioned in connection with the case include Peter’s son Rahul Mukherjea and Vidhie, daughter of Indrani and Sanjeev Khanna.

The police have also questioned Siddharth Das, biological father of Sheena and Mikhail Bora. Sheena was allegedly strangled in a car, then her body was burnt and dumped at a forest in Raigad, about 84 kms from Mumbai.

On October 2, Indrani was taken to J J Hospital from Byculla womens’ prison in an unconscious state, fuelling speculation that she had overdosed on anti-depressant drugs. But the probe by Inspector General (prisons) ruled out the possibility of drug overdose, poisoning or suicide bid.

On October 6, the 43-year-old was discharged and sent back to jail. CBI was permitted to question her in the jail.
